SPECIFICATION forming part of Letters Patent No. 527,484, dated October16, 1894.

Application filed May 29,1894. Serial No. 51 ,858. (No model.)

the mixture 0 and extended beyond the shell 7 To all whom it mayconcern.-

Be it known that I, OLE S. ERICKSON, a citizen of the United States,residing at Moscow, in the county of Latah and State of Idaho, haveinvented certain new and useful Improvements in Squirrel Exterminators;and Ido declare the following to be a full,

clear, and exact description of the invention,-

' and then explode and force such poisonous gas and smoke into all partsof the burrow.

It has also for its object to provide a shell of this kind of aninexpensive nature, which when ignited will first serve to kill off theanimals by the poisonous smoke and gases enerated and then rupture orbreak up the arrows by explosion.

My invention consists in a shell constructed in the manner hereinafterfirst described in detail and then specifically set out in the appendedclaims, reference being had to the accompanying drawings, in whichFigure l is a perspective view of my improved exterminator, and Fig. 2is a longitudinal section thereof.

Referring to the accompanying drawings, A indicates the shell proper,which in the practical construction is formed of paper, of a cylindricalshape, and preferably about ten inches long and seven-eighths of an inchin diameter. At its inner end the shell is loaded with a charge ofpowder B, on which is filled to a point near the upper end of such shella mixture of sulphur, powder and charcoal indicated by O, which mixtureis preferably moistened with nitric acid, such preparation beingintended, when ignited, to generate a poisonous gas and smoke.

E indicates a common fuse inserted into and through a cotton battingplug D, which closes the end ofthe shell, which in practice is thencrimped to hold the internal parts in place.

In operation after the fuse is ignited, the shell is placed, with fuseend foremost into the hole that leads to the animals burrow in theground; and as the mixture 0 becomes ignited it will first burn andgenerate a great quantity of poisonous gas and smoke, which, as the firereaches the powder charge, is forced by the explosion of such chargeinto all the parts of the burrow, the hole or entrance thereto being atthe same time ruptured and so broken up as to prevent other animalsfinding a home therein.

The cylinder into which the compound is placed may be formed of anysuitable material and desired shape, as it is obvious that such detailsin no wise affect the scope of the invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is e 1. An improved squirrel exterminator comprisinga shell, having an explosive compound at its rear end, an intermediatefilling of sulphur, powder and charcoal, moistened with nitric acid; acotton plug and a fuse inserted through the plug into the intermediatefilling, substantially as shown and described.

2. An improved squirrel exterminator comprising a paper shell or case,an explosive charge at the rear end of the same, a slow burning and gasgenerating mixture arranged next to said charge, said mixture consistingof sulphur, powder and charcoal, moistened with nitric acid, a cottonplug placed next to said mixture, and a fuse extending through the pluginto the mixture, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

.OLE S. ERICKSON.
